The particles are usually shown as ideal balls. However, this aesthetically appealing imagination goes beyond the laws of quantum physics. However, the "deterioration" of the electronic form is still not possible.
Last month, at Harvard last month, an experiment with the advanced cold molecule Electron Electric Dipole Moment was held. But because its essence and results can not be easily interpreted, the media penetrate infinitely. The researchers once again tried to "see" and measure the shape of the electron, but the accuracy of the instrument was not sufficient, and therefore the electron remains "round".
In the beginning, an electron is conceived as a point of space, without structure and shape, but with a clear negative charge. After that, in the development of science, he was still given a small angular momentum and a small magnetic field, which caused the problem. To find a magnetic field, you need two different poles, though slightly different from each other. That is, the electron must have even the smallest diameter in the particle physics, this parameter is called an electric dipole moment (EDM).
The size and shape of the electron depend on EDM. For example, it may look like a pear of pear or rugby pear. The standard model assumes that this is the case – even the theoretical EDM value is calculated: 10-38cm To approve the unit, and better still, negate it in practice and get new data. Unfortunately, although Harvard physicists managed to measure EDM unprecedentedly10-29cm, but one "saw" only a circle. The official formal electron is round, although it is a paradox.
Why is this frustrating? To form an electron in a complex form, so far it must be possible to work for unknown subatomic particles, which is very easy to find – at least confirm that they really exist and affect the micro-world. In addition, the standard model that describes electronic EDM is full of voids, and physicists have long dreamed of a theoretical reason to formally deny their postulates in order to offer new models and theories. Unfortunately, the electron is still round.
